real(DP),dimension(3),public igmcore_coordinate_conversion::geo_to_orth_pos ( real(DP),dimension(3),intent(in) geo_p )

Performs a coordinate conversion of a position vector given in a geographic coordinate to a cartesian coordinate.

Parameters:

[in] geo_p A position vector in a geographic coordinate system( $\phi$ (longitude), $\theta$ (latitude), (distance)).

real(DP),dimension(3),public igmcore_coordinate_conversion::geo_to_orth_vec	(	real(DP),dimension(3),intent(in)	geo_v,
		real(DP),dimension(3),intent(in)	geo_p
	)

Converts a vector from geographic to cartesian coordinate system.

Parameters:

[in]	geo_v	A vector in geographic coordinate system $(A_{\phi}, A_{\theta}, A_r)$ .
[in]	geo_p	A position vector in geographic coordinate system( $\phi$ (longitude), $\theta$ (latitude), (distance)).
